Iron, Gunpowder, and Spellcasters

Synopsis:Is magic really a wish-granting machine? No! In a universe where magic truly exists, its ultimate essence will certainly be as simple and beautiful as the laws of physics. This is the story of a mass-produced magical combat toolman who learns the ultimate essence of magic. But so what? Just as birds can fly without understanding aerodynamics, a magician doesn't need to understand the ultimate essence of magic to use it. Knowing the ultimate essence of magic doesn't mean the toolman can transform into a great magician. But the thirst for knowledge is human instinct, and curiosity is the first driving force of human civilization. Even with magic, which shouldn't have any logic, humans hope to understand its internal operating rules. Exploring the ultimate essence of magic needs no reason!The story in the book takes place in an era where iron and gunpowder dance together.
